Wild Mushrooms make Vitamin D!

Chanterelles in the wild are shown in the picture above. 

Mushrooms are apparently  only vegetarian food that can actually make Vitamin D…. because they have “pro-vitamin,” or precursor, called ergosterol that  converts into vitamin D when exposed to the sun’s ultraviolet (UV) radia­tion.  It works in a similar way to  how skin synthesizes the vitamin when it gets the right level of  sun exposure. Before you all go get tempted to buy lots in read on as It’s important to know that shop bought ones are mostly  commercially cultivated and nearly always grown indoors in the dark, which simply means their value of Vitamin D is  negligible.

In contrast, the  wild mushrooms you can foliage for such as  chanterelles, mai­take, and morels—are authentic and richer in Vitamin D because they get natural sun exposure and if left out longer will naturally come with a rich source of  vitamin D.

Over the past decade, sci­entists have been studying mushrooms and the impact of VU rays.  They have found that modest amount of UV from the natural sun or special VU lamps produce vitamin D in mushrooms and interestingly enough,  15 minutes of direct sun­light can produce 200 to 800 IU in 3 ounces of mushrooms (the  RDA is set as 600 to 800 IU although you can have more), regardless of type or season and at least 90 per­cent of  vitamin D is retained even after storage or when being cooked. The Whole button mushrooms have been researched to synthesise the least amount of Vitamin D; although when sliced have been demonstrated to be proficient D producers. Try this for yourselves.Place the mushrooms with the “gills” i.e. upwards and facing the sun to maximise the D production. The mush­rooms have been shown to discolour  and dry out a little during this process.

For many vegetarians since Mushrooms are a good protein source this makes sense or  If you like mushrooms, those that have been exposed to UV you may get more vitamin D,
